Preheat & Prep: Preheat oven to 375°F (190°C) and line a muffin tin with paper liners.
Mix Dry Ingredients: In a medium bowl, whisk together cake flour, sugar, baking powder, salt, and cocoa powder.
Mix Wet Ingredients: In a large bowl, combine melted margarine, milk, eggs, and vanilla essence. Whisk until smooth.
Combine: Gradually add the dry ingredients to the wet mixture, stirring gently until just combined. Avoid overmixing for tender muffins.
Add Chocolate Chips: Fold in chocolate chips evenly.
Fill Muffin Tin: Scoop batter into prepared muffin cups, filling each about ¾ full.
Bake: Bake for 18–22 minutes, or until a toothpick inserted in the center comes out clean.
Cool & Serve: Let muffins cool for a few minutes in the tin, then transfer to a wire rack. Enjoy warm or at room temperature.
